OIL-CUP.

Specification of Letters Patent.

Patented Dec. 17, i918.

Application filed November 30, 1917. Serial No. 204,594..

To all whom t may concern:

Be it known that I, EDMUND NOLAN, a citizen of the United States, and aresident of Detroit, in the county of Tayne and State of Michigan, haveinvented certain new and useful improvements in Oil-Cups, of which thefollowing is a specilication.

My invention relates to oil cups, and covers improved features ofconstruction and arrangement which enables such cups to be morepractically and easily used.

Oil cups are usually provided with a threaded end for screwing into atapped hole leading to the surface to be lubricated. Some of these cupsof the prior art have a rotatable cover provided with a side opening tobe brought into registration with a side opening through the cup body topermit the charging in of oil. l'n screwing these cups into the tappedhole the register-- ing oil holes of the cup will not always be in aconvenient position after the cup has been screwed into place. The coveris apt to become displaced to open the oil holes in which case oil canreadily escape or dust and dirt enter.

Among the important objects of my invention are therefore to provide acup in which there are no holes drilled through the cup body or cover;toprovide a cover or top which is hinged in such manner as to be rotatedaxially on the cup to be conveniently opened from any side thereof; toprovide an improved hinge support for the top preferably locatedentirely within the cup body to be rotatable therein; to provide ahinged support in the form of a spring frame which can be readilyinserted or withdrawn from the cup; and to provide spring means, insideof the cup, for yieldingly holding the top either in closed or openposition and tending to'snap the top shut after a short distance ofmovement thereof from its open vposition toward closed position.

The above features of the invention are embodied in a cup structuredisclosed on the accompanying sheet of drawings in which- Figure 1 is aside elevational view of the cup,

Fig. 2 is a side elevational view with the upper part in section onplane 2--2, Fig. 1,

Fig. 3 is a sectional view on plane 2-2,

Fig. 1, showing the cover in open position, an

Fig. 4 is a. sectional view on plane l-h Fig. 2.

The cup shown comprises the cylindrical oil containing body 10, thewrench receiving polygonal shank 11, and the threaded end 12 forscrewing into tapped holes. A short distance below the upper edge of thebody 10 is the annular rectangular groove 13 forming a seat for theframe F which supports the cover C. The frame F is bent up from a bandof sheet metal, preferably spring steel, and is of general U-shape, thebase 14 and the sections 15 and 16 of the sides formingr a rectangularpocket 17, the sides beyond the pocket extending first laterally at 18and 19, the ends 20 and 21 being arcuate to fit in the groove 13 inwhich the base 14 of the frame also engages. Before insertion of theframe in the groove its sides are rst spread a trie and then when theframe is slipped into the groove its eXpansion will cause it to beclamped in the groove against axial displacement but permitting it torevolve readily. A flat spring 22 has at one end the downwardlyextending wings 23 and 24 which extend into the pocket 17 and againstthe sections 15 and 16 of the frame F, a hinge pin 25 extending throughthese sections and the wings. rlhe spring at its other end is rigidlysecured against the under side of the cover C as by means of a rivet 26.The spring is normally fiat but when it is applied its hinged end isheld a distance away from the top C so that the spring will tend to holdthe rear end of the top against the upper edge of the body 10. When theaxial component of the spring pull predominates the spring will tend toswing the cover to closed position, while when the diametral pullpredominates the spring will tend to hold the cover in the open positionshown in Fig. 3. The top C is provided with a peripheral flange 27 forengaging with the oil cup sides and the end 28 of the spring 22preferably projects a distance outwardly through the slot 29 formed inthe flange, the spring being thus locked against turning in the rivet.The projecting end also forms a finger abutment for enabling the top tobe readily raised to open position. Then fully opened the edge of theflange 27 abuts against the side of the cup l0 as shown in Fig. 3. Thearrangement is preferably such that when the cover is in open position aslight touch or jar on the cover will start it and permit a spring tosnap it into closed position.

My improved cup is very practical in that no matter how far the body isturned in screwing the cup into place on its support the top can berotated in a convenient position for opening. The supporting str cturefor the top is all inside of the cup leaving the outside of the cupentirely free from attachments. The supporting mechanism is also verysimple in its construction and can be very readily inserted into thegroove 13. Oil in the cup will lubricate the groove as well as the hingeconnection and the supporting frame can therefore r .adily be rotated atany time and the top freely moved into open or closed position. rThehinged cover eliminates all side openings in the cup or top and whenclosed seals the cup against oil escape vor the entrance of dust anddirt.

l do not of course desire to be limited to the details ot constructionand arrangement shown and described as changes and niodiiications couldno doubt be made which would still come within the scope of myinvention.

I claim as follows:

1. ln an oil cup, the combination with an oil containing body, of atrame detachably secured within the body and axially rotatable therein,and a top for thei cup hinged to said frame and rotatable therewith.

2. The combination with an oil cup frame, ot a cover thereof, a tramerotatable on said cup around its axis, and a spring secured to saidcover at one end and hinged to said frame at its other end. y

3. The combination with an oil cup, or a spring frame at the insidethereof clampingly engaging therewith and rotatable about the cup axis,a spring hingedr at its inner end to said frame, and a cover for the cupsecured to the other end of said spring whereby said cover may be swungto open and close said cup and may be rotated with said frame.

fl. The combination with a cylindrical receptacle having an annularinternal groove below its upper edge, a supporting frame engaging insaid groove to rotate around the4 receptacle axis, a hinge springpivote-,d Vat its inner end to said frame, and a receptacle rigidlysecured to the outer end oit Copies of this patent may be obtained forve cents each, by addressing the cover for the said spring whereby saidcover may be swung to open or close the receptacle and may be rotatedaxially. Y

5. The combination with a receptacle, of a supporting frame thereinrotatable about the receptacle axis, a dat hinge springpivoted at itsinner end to said frame at one side of the receptacle, a cover for thereceptacle rigidly secured to the hinge spring at its other end, thehinge end of the spring being held away from the cover whereby saidspring will tend to hold the hinged end of the cover against theentrance edge of the receptacle.
